Have a look at a pre4vious thread regarding a lathe foot switch.
Kevin
Thank you for taking the time to respond.
I remember that thread but it dealt with a foot switch for a particular lathe whereas I'm looking for an extension lead with a foot switch in the middle so that I can connect whatever power tool I'm using - the drill press was an example - through the foot switch.
I understand that this sort of thing is commonly available in the Untied States (but they have mains supply at a lower voltage)
As I wrote, Axminster sell something entirely suitable for £90 and I guess that another company must offer something similar (but at a price that's more reasonable)
I thought that one of the well-informed and helpful people who read this might be able to point me at a ready made solution.
With best wishes and thanks again.
